Description

[Detailed Description of the Invention] 1. Industrial Application Field The present invention relates to a liquid dispensing container for storing, for example, soft drinks.

1. Conventional technology Conventionally, containers made of synthetic resin have been widely used, and containers made of synthetic resin are placed inside an outer box made of cardboard, or containers made of synthetic resin paper are attached to the inner surface of the outer cardboard box. It has been known.

Problems to be Solved by the First Invention The above-mentioned container made of Hewei resin has the disadvantage that when incinerated, it generates harmful gases and burns at high temperatures, damaging the incinerator.

As a container that can eliminate these drawbacks, there is the above-mentioned container, such as a synthetic resin bag placed inside a cardboard outer box, but it is difficult to attach a spout neck for dispensing the stored contents to this container. In addition, even if the mouth and neck are attached, if the outer box and the bag are not integrated, the bag will bend and move in an irregular shape in the outer box when dispensing the contents. Therefore, it is difficult to pour out the bag, and when the outer box and the bag are to be integrated, it is troublesome to join them together.

This proposal eliminates the above drawbacks and uses a thin container body made of synthetic resin and an outer box made of cardboard, which generates less harmful gas, eliminates the risk of damage to the incinerator, and makes it easy to attach the neck and mouth. It is easy to integrate the thin container body and the outer box made of cardboard, and therefore it is also easy to pour out the contents from inside the container.

1. Means for Solving Problem 1 The proposed container includes a thin container body made of synthetic resin, a holding member made of cardboard, a liquid pouring cap with a nozzle, and an outer box made of cardboard,
and a removal wall formed on a part of the outer box wall.

The thin container body 1 is made of synthetic resin, and extends from the bottom wall 2 to the peripheral wall 3.
is made to stand upright, and a mouth portion 5 having a fitting groove 6 is bored out from the upper end of the peripheral wall via the shoulder portion 4 on the outer periphery of the base.

The holding member 10 is made of cardboard, and the mouth and neck portion are inserted into a through hole bored in the plate portion 11, and the peripheral edge of the through hole is fitted into the fitting groove 6, and the peripheral edge of the plate portion is fitted into the fitting groove 6. From there, a joining tube 12 is vertically installed.

The cap 13 has a nozzle 14, and the cap peripheral wall is fitted into the mouth portion 5.

The outer box 19 has a peripheral wall 18 standing up from a bottom wall 23, and the thin container main body 1 is fitted inside the peripheral wall 18.

The outer surface of the joining tube 12 is joined to the upper inner surface of the peripheral wall 18, and a top wall 20 is stretched over the upper end of the peripheral wall 18.

The removal wall 21 is formed by providing a break line 22 around the wall of the cardboard outer box, including the wall in front of the nozzle.

In one operation, the contents stored in the thin-walled container body are poured out by removing the wall portion 21 by cutting the break line 22 and opening the front of the nozzle.

The cardboard holding member has the through-hole peripheral portion fitted into the fitting groove 6 of the mouth and neck portion, and the joining tube 12 is joined to the upper inner surface of the cardboard outer box peripheral wall 18, so that the container body 1 and outer box 19
are integrally joined to prevent the container body from being removed from the outer box.

Embodiment 1 The container body 1 is preferably formed of a biaxially stretched thin-walled bottle made of saturated polyester resin.

The container has a peripheral wall 3 standing up from the periphery of the bottom wall 2, and an opening 5 protruding from the upper end of the peripheral wall via a shoulder 4.
A fitting groove 6 is provided around the outer periphery of the base of the mouth portion 5.

The fitting groove may be formed between the outward flange 7 provided below and the engagement protrusion 8 provided above.

A cap screw 9 is attached to the outer surface of the mouth and neck.

Only the mouth and neck part is made thick like the mouth and neck part of ordinary synthetic resin containers, but the other parts are made thin.

A holding member 10 made of cardboard is fitted into the mouth and neck of the container.

This member has a plate part 11 having a through hole, and a joining tube 12 is suspended from the periphery of the plate part. the part into the fitting groove 6.

In order to increase the rigidity of the plate portion 11, it is preferable to form a truncated pyramid shape, a truncated conical shape, or the like as shown in the drawing.

A liquid pouring cap 13 with a nozzle is fitted into the mouth and neck portion 5 .

The cap may be any conventionally used cap.

An aluminum seal 15 is provided on the tip surface of the nozzle 14 for sealing, and a nozzle cap 16 is screwed onto the outer surface of the nozzle tip.

Note that 17 is a backing.

The thin-walled container body is placed in a cardboard outer box 19 by joining the joining tube 12 of the cardboard holding member to the upper inner surface of the peripheral wall 18.

The box has a peripheral wall 18 standing up from the periphery of the bottom wall 23 and a top wall 20 at the upper end of the peripheral wall, and is assembled after being cut into an unfolded state with a glue allowance added, like a conventional paper box.

A portion of the cardboard box that includes the nozzle front portion described above is used as a wall portion 21 for removal.

The wall has a break line 2 on its periphery for easy removal.
2 will be provided around.

In the illustrated example, the peripheral wall portion 21 is removed at each portion of the peripheral wall and the top wall.
However, the top wall above the peripheral wall portion to which the cardboard holding member is joined may also be removed.

1. Effects of the invention The present invention has the above-mentioned structure, and since the thin container body made of synthetic resin and the outer box made of cardboard are integrated, no harmful gases are generated compared to conventional synthetic resin containers. Since the combustion temperature can be lowered and the combustion temperature can be lowered, there is no risk of damage to the furnace.Also, since a thin synthetic resin container body is fitted inside the outer box instead of a synthetic resin bag, it is less expensive than conventional bags. Thus, it does not become difficult to attach the mouth and neck, and when pouring out the contents stored in the container main body, there is no possibility that countless irregularly shaped bends occur, making it difficult to pour out the contents.

Furthermore, the container body 1 made of synthetic resin and the outer box 19 made of cardboard are
The opening and neck of the container main body is inserted into a throughhole drilled in the plate part 11 of the cardboard holding member, and the peripheral edge of the throughhole is fitted into the fitting groove 6 provided around the outer surface of the base of the opening and neck. In addition, since the joining tube 12 suspended from the periphery of the plate part is joined to the upper inner surface of the outer box peripheral wall 18, it is only necessary to glue the cardboard to each other, which is a special problem such as when bonding synthetic resin and cardboard. The container body made of synthetic resin and the outer box made of cardboard can be easily connected together without using any adhesive.

Furthermore, since the wall section including the wall section in front of the nozzle of the outer box is provided with a removal wall section 21 formed with a break line 22 around it, the front section of the nozzle can be easily opened by removing the wall section. Contents stored in the container can be poured out.
